Building, restoration, and repair with epoxy

I made a difficult rear-hatch repair on my 2007 aluminum SeaArk 1872 MVJT (modified V-jet tunnel) center console using WEST SYSTEM G/flex Epoxy.

The year before I bought it, my SeaArk center console had undergone a complete rebuild. The entire inside of the boat was sprayed with Line-X® Protective Coating, which makes clean-up super easy but prohibits any additional welding to the aluminum.

After developing the Aluminum Boat Repair Kit we have had calls from customers saying they have a larger boat and cannot easily turn it over as recommended to work on the seams and rivets. They ask “will this kit still work on my boat?” The answer is, yes, it will. It will be a little messier but will work the same way upside down or right side up. Continue reading →

Big Jon (BJ) serves as a reel for retrieving and letting line attached to floating planer boards in and out from a boat while trolling. Planer boards are used to get fishing lures off to the side of the hull so the lures aren’t following directly behind the boat while trolling for walleye. The further the planer board is reeled out, the further the lures are from the side of the hull. BJ has served Tom and Lorraine Klinski well but recently developed some cracks in what appears to be a black nylon plastic. Continue reading →

In January of 2015, we stopped offering the 860 Aluminum Etch Kit in the WEST SYSTEM product line. Before making that decision we ran a series of tests that compared bond strength of 105 Resin/206 Hardener and G/flex 650 Epoxy on aluminum surfaces prepared a variety of ways. As usual, we used the PATTI (Pneumatic Adhesion Tensile Test Instrument) to test adhesion. Continue reading →

When we started testing G/flex Epoxy as a solution to leaky seams and rivets in aluminum boats, we put out a company-wide call for test boats. John Kennedy offered his old 15′ Michi-Craft canoe, saying he would bring it down from his cabin at the end of hunting season. Not smiling, he asked a few weeks later “just how big a repair we could handle.” It turned out John jack-knifed his utility trailer on an icy road, punching a fist-sized hole in the stern quarter of the canoe (Photo 1). Ouch. Continue reading →

We wanted to experiment with using G/flex to fix leaking aluminum boats. I was quite surprised to find that every aluminum boat owner I talked to said they had some sort of leak. Within three hours, I had several co-workers volunteer their aluminum boats for the experimental fix using G/flex. Continue reading →

Ten years ago, I replaced the plywood transom in my 16′ aluminum fishing boat. It had gone bad due to the motor mount screw pads crushing the wood from over-tightening, and from shock loads involved in hanging a motor off the back of a boat and traveling down the road at 70 mph. Continue reading →

Some people just have a knack for things. We commonly say that someone may have an “eye” for beauty, an “ear” for music, or a “taste” for art, and now you can have a…“nose” for speed. Nose cones on outboard and sterndrive lower units are common in the world of boat racing. Whether it be outboard hydroplane racing, outboard performance craft (tunnel hulls), offshore powerboats, or customized recreational boats, all have factory built “speedo” lower units, which are very fast, but expensive. However, adding a nose cone to your existing lower unit is affordable, quick, and fun to do. Continue reading →

A common source of problems on open runabouts and pontoon boats is the cockpit floor or deck. This part of the boat is usually just a layer of plywood screwed down to the top of stringers and frames. Many have a layer of carpet or vinyl flooring material glued onto the plywood. Continue reading →
